Digital certificate belonging to Realtek Semiconductor that was used to sign a pair of drivers fro the new Stuxnet rootkit has been revoked by VeriSign. The certificate was revoked Friday, several days after news broke about the existence of the new malware. Microsoft oficials also said that they expect other attackers to begin using the infection method that StuxNet uses, relying on the.lnk shortcut files to launch and hide itself. Microsoft said it is investigating the flaw and looking at possible solutions, however there was no clear indication that the company intends to patch the flaw.
